Part C: Multiple TRUE/FALSE 3. Which of the following statements about velocity and/or speed are TRUE? List all that apply.
- Velocity is a vector quantity and speed is a scalar quantity.
- Both speed and velocity refer to how fast an object is moving.
- Person X moves from location A to location B in 5 seconds. Person Y moves between the same two locations in 10 seconds. Person Y is moving with twice the speed as person X.
- The velocity of an object refers to the rate at which the object's position changes.
- For any given motion, it is possible that an object could move very fast yet have an abnormally small velocity.
- The phrase "30 mi/hr, west" likely refers to a scalar quantity.
- The average velocity of an object on a round-trip journey would be 0.
- The direction of the velocity vector is dependent upon two factors: the direction the object is moving and whether the object is speeding up or slowing down.
- The diagram below depicts the path of a person walking to and fro from position A to B to C to D. The entire motion takes 8 minutes. The average speed for this motion is approximately 11.3 yds/min.
- For the same diagram below, the average velocity for this motion is 0 yds/min.
